In a right triangle, if one angle measures 30 degrees, what is the measure of the other acute angle?

In a right triangle, the sum of the measures of the three angles is always 180 degrees. Since one of the angles is a right angle, measuring 90 degrees, the sum of the other two acute angles must be 90 degrees as well.

Given that one angle measures 30 degrees, you can find the other acute angle by subtracting 30 degrees from 90 degrees:

90 degrees - 30 degrees = 60 degrees.

Thus, the measure of the other acute angle is 60 degrees. This makes the correct answer 60 degrees, as it satisfies the requirement that the two acute angles of a right triangle sum to 90 degrees.
